Abstract: L'invention se rapporte à un système pour commander un précipitateur électrostatique (10, 12) conçu pour être alimenté par une source de courant alternatif (60). Ce système comprend un organe pour la régulation (Q2, Q4, 14) d'au moins un paramètre de fonctionnement du précipitateur, en réponse à au moins un signal de commande, ainsi qu'un organe de mesure (110, 120) couplé au précipitateur de façon à fournir des signaux de mesure qui correspondent à au moins une tension secondaire du précipitateur et un courant secondaire du précipitateur. Un processeur (16) couplé à l'organe de mesure (110, 120) et à l'organe de régulation génère les signaux de commande. Le processeur (16) sert à échantillonner des valeurs discrètes successives des signaux de mesure qui correspondent à la tension secondaire et au courant secondaire pendant un demi-cycle individuel de la source de courant alternatif (60), afin de déterminer les conditions de fonctionnement actuelles du précipitateur (10, 12) sur la base au moins des valeurs échantillonnées, de façon à prévoir les conditions de fonctionnement du précipitateur (10, 12) pour le demi-cycle suivant de la source de courant alternatif (60), sur la base au moins des conditions de fonctionnement actuelles, et de façon à faire varier sélectivement ledit signal de commande par le demi-cycle suivant de la source de courant alternatif (60) en réponse aux conditions de fonctionnement prévues.

Abstract: Un procédé permet notamment de mesurer des écartements situés dans la zone d'ambiguïté d'émission et de réception d'ultrasons. L'unité d'émission et de réception d'ultrasons comprend un seul transducteur ultrasonore utilisé en mode à échos d'impulsions. On détermine premièrement le moment te1 où le premier écho est reçu. Si ce moment se situe hors du double temps mort 2tT, la mesure est claire et la durée de propagation du son, qui est proportionnelle à l'écartement entre l'unité d'émission et de réception d'ultrasons et l'objet, est donnée. Autrement, la durée de propagation du son est déterminée à partir de la différence entre les moments où deux échos multiples successifs du même objet sont reçus.

Abstract: Formed on a side wall (2) of a processing liquid vessel placed on a movable table is a window portion, through which an arm member (31) extends and which permits the arm member (31) to move relative to the processing liquid vessel in a direction (X-direction) perpendicular to an axial direction of the arm member (31). The window portion is sealed by a sealing mechanism (S) which includes a seal plate (6) engaged with the arm member (31). On the other hand, a partition member (70) is provided inside of the processing liquid vessel so as to cover the sealing mechanism (S). When a closed space defined by the partition member (70) is filled with a clean processing liquid which is supplied from the outside through liquid feed pipes (74A, 74B), the clean processing liquid isolates the sealing mechanism from a dirty processing liquid in the processing liquid vessel. The processing liquid flows into the processing liquid vessel through a slight gap between a window portion (71) provided in that portion of the partition member (70), through which the lower arm member (31) extends, and a bellows (72) which closes the window portion (71).

Abstract: The invention relates to a continuously variable transmission, in particular for a motor vehicle, provided with a control for the transmission ratio of the transmission, which control in a first operating mode controls the transmission ratio on the basis of one or more input signals and in a second operating mode controls the transmission ratio, for example on the basis of an external signal originating from the driver of the motor vehicle, along one or more control curves (C1-C5) of one or more sets of control curves, possibly within rotational speed limits (n min ,n max ) imposed on the input speed (n eng ) of the transmission. One or more control curves and/or one or more rotational speed limits are a function of the input speed of the transmission in such a way that, in accordance with said functions, the input speed of the transmission is not zero for a notional output speed of the transmission of zero. By this means the drive characteristics of the transmission are appreciably improved, coupled with improved efficiency and optimum power.
